Definitions

  • the present invention relates to electronic cigarettes, and particularly to a refillable atomizer and an electronic cigarette using same.
  • Atypical refillable atomizer includes a liquid chamber with a liquid inlet.
  • the liquid inlet is usually sealed by an end piece. To inject tobacco liquid, the end piece is first opened.
  • the refillable atomizer when a user of the refillable atomizer injects tobacco liquid into the refillable atomizer, the refillable atomizer may be over turned due to carelessness. In this case, the tobacco liquid may leak from atomizer, thus rendering unsatisfactory.
  • GB 2512329 A relates to a simulated cigarette having a generally cylindrical cigarette like housing with a main axis, the housing containing a reservoir of a pressurised inhalable composition extending along a substantial portion of the housing, the reservoir having a reservoir outlet at one end which is selectively closed by an outlet valve, the outlet valve being operable to allow the composition to flow from the reservoir outlet to an inhalation outlet at the outlet end of the device.
  • US 20100242975A1 relates to a system comprising a simulated cigarette device and a refill unit.
  • US 2014261408A1 relates to a cartridge for an aerosol delivery device such as a smoking article.
  • the present invention provides an atomizer according to independent claim 1. Further improvements are recited in the dependent claims.
  • outside refers to a region that is beyond the outermost confines of a physical object.
  • inside indicates that at least a portion of a region is partially contained within a boundary formed by the object.
  • substantially is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder.
  • comprising when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
  • a refillable atomizer 10 includes a housing 100, an atomizing unit 300 in the housing 100, and a receiving chamber 101 defined in the housing 100.
  • the receiving chamber 101 is configured (i.e., structured and arranged) for storing tobacco liquid filled by an external injector.
  • the receiving chamber 101 includes a liquid inlet 102.
  • the injector usually includes a long and thin pinhead, and the pinhead may be plugged into the receiving chamber 101 via the liquid inlet 102. In this way, the tobacco liquid is injected into the receiving chamber 101.
  • the atomizing unit 300 is adapted for generating aerosol from the tobacco liquid.
  • the atomizer 10 further includes a resilient valve 103 sealing the liquid inlet 102. The valve 103 is pushed open by the injector, so that the tobacco liquid is injected into the receiving chamber 101. When the injector is moved away from the liquid inlet 102, the valve 103 restores to its original shape to seal the liquid inlet 102 again.
  • the receiving chamber 101 extends along an axial direction of the housing 100, and the valve 103 is positioned in the liquid inlet 102.
  • the atomizing unit 300 is arranged in a bottom opening of the receiving chamber 101.
  • the valve 103 is made of resilient material, for example, silica gel. If the atomizer 10 is overturned during injection, the injector leaves from the liquid inlet 102, and the valve 103 restores to its original shape to seal the liquid inlet 102, thus avoiding liquid leakage from the liquid inlet 102.
  • the atomizer 10 further includes a mouthpiece 200 detachably connected with the housing 100.
  • the mouthpiece 200 includes a sealing part 203 configured for sealing the liquid inlet 102.
  • the mouthpiece 200 is fixedly connected to the housing 100 via screw threads, and the mouthpiece 200 includes a screw structure 202. When filling in tobacco liquid, the mouthpiece 200 should be detached first.
  • An air pipe 105 is further provided in the receiving chamber 101.
  • One end of the air pipe 105 is connected to the atomizing unit, and the other end of the air pipe 105 is connected with the mouthpiece 200.
  • the mouthpiece 200 defines an air outlet 201.
  • the aerosol is inhaled via the air outlet 201.
  • An elastic element 110 abuts against an end of the air pipe 105 connected with the atomizing unit 300.
  • the elastic element 110 is a spring.
  • the elastic element 110 is capable of driving a top end of the air pipe 105 to abut against the mouthpiece 200, and capable of driving the air pipe 105 to move upwards axially when the mouthpiece 200 is screwed off.
  • the atomizer 10 includes a liquid storing chamber 106 arranged under the receiving chamber 101. At least one liquid hole 107 communicates the liquid chamber 106 and the receiving chamber 101.
  • a first seal ring 108 sleeves a bottom end of the air pipe 105. The first seal ring 108 is capable of moving together with the air pipe 105 to seal or open the liquid hole 107.
  • a base 109 is provided at a bottom end of the air pipe 105, the first seal ring 108 is fixed on the base 109, and the elastic element 110 abuts against a bottom surface of the base 109.
  • a top end of the atomizing unit 300 is hermetically connected with the air pipe 105, and is axially movable relative to the air pipe 105.
  • the valve 104 includes a casing main body 1041 and a deformable part 1042.
  • the casing main body 1041 nests the air pipe 105.
  • the deformable part 1042 extends outward from the air pipe 105.
  • a step part 103 is provided in the liquid inlet 102, and the deformable part 1042 abuts against a bottom surface of the step part 103.
  • the injector is plugged into the liquid inlet 102, the deformable part 1042 is deformed and pushed open.
  • the deformable part 1042 restores to its original shape, and tightly abuts against the bottom surface of the step part 103, thus sealing the liquid inlet 102 again.
  • the sealing part 203 seals the liquid inlet 102, and the mouthpiece 200 forces the air pipe 105 to move down axially.
  • the first seal ring 108 is also driven to move downwards, and the liquid hole 107 is opened, so that the tobacco liquid in the receiving chamber 101 can flow into the liquid storing chamber 106.
  • the atomizing unit 300 can absorb the tobacco liquid from the receiving chamber 101, and work normally.
  • the valve 104 is also moved down with the air pipe 105.
  • the atomizing unit 300 includes a main body 301, and the main body 301 defines an atomizing chamber 303. At least one liquid conducting body 304 and a heating element 305 are arranged in the atomizing chamber 303. The heating element 305 is in contact with the liquid conducting body 304. The liquid conducting body 304 is configured for conveying the tobacco liquid to the heating element 205. In the present embodiment, three liquid conducting bodies 304 are arranged in parallel in the atomizing chamber 303. The liquid conducting bodies 304 are made of porous material, e.g., glass fiber.
  • the heating element 205 is a heating wire wound around one or more liquid conducting bodies 304. The heating wire heats the tobacco liquid to form aerosol.
  • a second seal ring 302 nests an upper end of the main body 301.
  • the upper end of the main body 301 is inserted into the air pipe 105, and is hermetically connected with the air pipe 105 via the second seal ring 302.
  • the upper end of the main body 301 is slidable relative to the air pipe 105.
  • the atomizing unit 300 is an independent component. When broken, the atomizing unit 300 may be replaced by a new one.
  • a first contact electrode 306 and a second contact electrode 307 are arranged at a bottom end of the main body 301, and are insulated from each other by an insulated sleeve 308.
  • the first contact electrode 306 and the second contact electrode 307 are electrically connected with two ends of the heating element 305, respectively.
  • the first contact electrode 306 and the second contact electrode 307 are configured for connecting to two electrodes of a power supply 20 (see FIG. 5 ).
